My invention relates to improvements in safety razors and has'particular reference to Y the class in which a strop :is inserted' through` the frame for stropping the bladewlienthe 5 razor is v reciprocated Yalong the strop. In .this class of razors, v'comnmnly known as the l Auto yStrop razor,lit has been,y customary to provide strop-tensioning means ontli'e frame on opposite sides ofa'roller that engages'the Y .strop for causing rotation or rocking l'ofthe .Y 'bladek holder, Y and-*such -stropQtensio'ning means andi-'011er 'havezbeen in permanent're "l lation for receiving the strop therebetween;'.-

Strops: lfor :such vsafety. Vrazors*frequentlyv y y vary in thickness andfif the strop is toofthickit? is more or less inconvenient in stroppingtheblade;y f n v An object of my invention is' to vprovide ya vsafety razor ofthe classset forth with means movably guiding the blade-holder operating-A roller with respect to the stiropten'sioningv means and to resiliently press therollerfto-` ward the strop, wherebyv rstrops of varying thickness may be readily vaccommodated in v the razor-and thestropping of thevbladewill be facilitated. s

" In carrying outmy invention I providea main frame Vhaving strop-tensrolling means.

` and a blade guard,- 'a second frame carrying a blade holder "and: strop-engaging roller gearedtogethenmeans movably guiding saidv framesV to permitlmovementofthe roller toward and from a strop, and means'normally tending to move said roller toward the'strop,

`3.5 preferably in a resilientmanner, whereby the roller may move` 'relatively toL thestrop-ten'- Vsioning means to accommodate strops of varying thicknesses to permit ready reciprocatio'nof the yrazor along the strops.v

vkMy invention also comprises novel details of improvement that will be more fully hereinafterv set forth and then 'pointed outgin the 1ClaimS.;:-:-- l Y t.

.Whenfthe parts described are n otl used o'r stropping the strip or plate 4a willbe pressed by spring 13 'against the base 1a, as illustrated in Fig. 2, `and when the strop is passed through the razor it will bear against the tensioning means 1*?, 1c' andagainst the Vroller 7,

i f and to be kswung away fromthe blade to release the latter, as shown in Fig. 7 a. The blade holder 9b isshown provided with spaced ,studs orVVV projections 14 adapted to pass 1 through holes 9e in the'blade and through l holesk9g in member 9 to retain the blade in '50.

"shaving position `with -the heel of the blade abutting against the 4shaft 9m., between plate 9b and an angularlyfdisposed flange or projection 9t providing a space 15in which the y'inner portion of the blade is guided and located,1(-Figs.- 7 and 7 a).

' A 'guard for the blade edgeis indicated at edge toreleasethe blade for stropping and for inserting new blades, as illustrated in Fig. 3. The guard 16 is shown provided with a laterally projecting portion 16 that is adapted to engage the strop-tensioning member 1b to retain the guard frictionally in set position, due to the tension between the parts 16 and 1b,ras illustrated in Fig. 6. A 'finger piece 16C extends from the guard on the side of the handle opposite the guard, being pro- Yvidedrwithl an opening 16d, (Fig. 2) movably receiving the handle, whereby the guard may be manipulated.
